An improved tuning method for fixed interval musical instruments is provided. This Precise Temperament tuning method provide mathematically consistent intervals between notes to prevent dissonance within chords while retaining the esthetics of pure tones associated with Western music.

Embodiments pertain to a method for use with a musical piece, or part thereof, comprising: presenting, by at least one client device to a plurality of users, a corresponding plurality of sequences of musical symbols to be cooperatively played by the plurality of users using a plurality of instruments; capturing instrument outputs produced by the plurality of instruments to generate audio data descriptive of the captured instrument outputs; analyzing the audio data for determining a level of correspondence between the captured instrument outputs and the plurality of musical symbols presented to the plurality of users; and presenting, based on the level of correspondence, an adapted or non-adapted sequence of music symbols to at least one of the plurality of players.

A signal processing device includes an electronic controller including at least one processor. The electronic controller is configured to execute a reception unit, a generation unit, and a processing unit. The reception unit is configured to receive first time-series data that include sound data, and second time-series data that are generated based on the first time-series data and that include at least data indicating a timing of a human action. The generation unit is configured to generate, based on the second time-series data, third time-series data notifying of the timing of the human action. The processing unit is configured to synchronize and output an output signal based on the first time-series data and an output signal based on the third time-series data, such that the timing of the human action for the first time-series data and the timing of the human action for the third time-series data match.

A method includes displaying, by an electronic device, a first interface, where the first interface includes a recording button used to record a first song, obtaining, by the electronic device, accompaniment of the first song and feature information of a cappella of an original singer, starting to record a cappella of the user that is sung by the user, and displaying, by the electronic device, guidance information on a second interface based on the feature information of the a cappella of the original singer, where the guidance information guides one or more of breathing and vibrato during the user's singing.

Systems and methods are disclosed for generating color sets based on musical concepts of pitch intervals and harmony. Color sets are derived via a music-to-hue process which analyzes musical pitch data associated with musical input to determine pitch intervals included in the music. Pitch interval angles associated with the pitch intervals are applied to a tuned hue index to identify hue note ordered within the index which are separated by a hue interval angle similar to the pitch angle associated with the analyzed pitch data. The systems and methods provide for the creation of color sets which are analogous to musical chords in that they include multiple hue notes selected based on hue interval angles derived from musical interval angles associated with the received musical input.

The disclosure provides a method for generating action according to an audio signal and an electronic device. The method includes: receiving an audio signal and extracting a high-level audio feature therefrom; extracting a latent audio feature from the high-level audio feature; in response to determining that the audio signal corresponds to a beat, obtaining a joint angle distribution matrix based on the latent audio feature; in response to determining that the audio signal corresponds to a music, obtaining a plurality of designated joint angles corresponding to a plurality of joint points based on the joint angle distribution matrix; and adjusting a joint angle of each of the joint points on the avatar according to the designated joint angles.

Measures (for example, methods, systems and computer programs) are provided to evaluate a percussive performance. Percussive performance data captured by one or more sensors is received. The percussive performance data represents one or more impact waveforms of one or more hits on a performance surface. The one or more impact waveforms are analysed. The analysing comprises: (i) identifying one or more characteristics of the one or more impact waveforms; (ii) classifying the one or more hits as one or more percussive hit-types based on the one or more characteristics; and (iii) evaluating the one or more percussive hit-types against performance target data. Performance evaluation data is output based on said evaluating.

A system for fractionally representing time signature for use with digital device includes a user interface that enables a user to enter a first number to represent the number of beats per bar; and to enter a second number to represent the number of divisions per beat. The system uses a processing device to run a set of transcription rules to the first and second numbers in response to user selected inputs. A graphical output is used to display a visual representation of the desired fractional output is displayed. The system also includes a method for fractionally representing time signatures with the steps of entering, via an electronic processing device, a first and a second number where the first number represents the number of beats per bar and the second number represents the number of divisions per beat and displays the result on an electronic display.

In a musical performance support system including a sensor device that is attached to a musical instrument and an operation device that is able to perform wireless communication mutually with the sensor device and is able to perform communication with an instructor terminal of an instructor via a server, the sensor device transmits a detection signal detected by an acceleration sensor that has at least to detection axes to the operation device, the operation device generates practice result information of musical performance of a user using the musical instrument and transmits the practice result information to the server, and the operation device receives guidance information in response to the practice result information from the instructor terminal through the server and causes display means to display the guidance information.
